Altcoins outpace majors on thin liquidity: the risk numbers

What happened

The CoinDesk 80 is an index of smaller tokens. According to CoinDesk, bitcoin traded under $83,500 after topping $84,000 on Sunday. Ether sat at $2,560 after a gain of around 2.5%.

The key finding is about liquidity. One year after the Oct. 10, 2025 flash crash, dollar order-book depth for bitcoin and ether is back at pre-crash levels, CoinDesk research found. Altcoin liquidity has kept eroding. So the outperformance sits in the least liquid corner of the market.

Joshua de Vos, research lead at CoinDesk, summed it up: "Market makers have returned to majors".

The numbers in context

Tradevo's figures use Bybit daily closes as of 2026-10-12, with changes over 7, 30 and 90 days and a simple 50-day average of closes.

• BTC: last close $82,780; down 3.5% over 7 days, up 7.1% over 30 days, up 27.8% over 90 days.
• BTC: 4.4% below its 90-day high close of $86,616; 31.8% above its 90-day low of $62,823; 84% of the way through the 90-day range; above its 50-day average of $81,064 by 2.1%.
• ETH: last close $2,533; down 6.5% over 7 days, up 0.3% over 30 days, up 32.1% over 90 days.
• ETH: 8.8% below its 90-day high close of $2,776; 37.5% above its 90-day low of $1,842; 74% of the way through the 90-day range; below its 50-day average of $2,558 by 1.0%.
• Flows: US spot bitcoin ETFs lost a net $681 million last week, the biggest weekly drain since June, per SoSoValue. Spot ether ETFs have had no inflow day since Sept. 28, a nine-day outflow streak, the longest since June.

Put together, the majors have the depth but not the inflows, and the smaller tokens have the price gains but not the depth.

Why depth matters for a stop

Order-book depth is the amount of resting buy and sell orders near the current price. Deep books absorb a market order with little price change. Thin books do not. A stop-loss becomes a market order when it triggers. In a thin book, it can fill well past the stop level. The gap between the planned and actual exit is slippage.

That means the real risk on an altcoin trade can be larger than the distance to the stop suggests. A move up on thin liquidity can reverse on thin liquidity too.

What this means for position size

Size follows the distance to the stop, not conviction. On a thin market, the honest distance to the stop includes expected slippage. A trader who keeps the same position size on a smaller token as on bitcoin is taking more risk per trade, even if the stop distance looks identical on the chart.

Two general principles follow. First, measure risk per trade from the realistic exit, not the ideal one. Second, when liquidity is poor, a smaller size keeps the loss within the plan if the fill is worse than expected. Neither principle says anything about direction.

What to watch next

Markets are focused on Wednesday's US consumer price index release. Oil is a side factor: WTI futures slipped around 2% to $90 a barrel. The trigger was a statement by Donald Trump that Russia will release diesel, 300,000 metric tons, onto world markets. Watch whether ETF flows turn and whether altcoin depth recovers alongside prices.
